Question

If all photosynthesizing organisms were removed from the planet would animals still be able to perform cellular respiration?

Answer 1

Answer:

No

Explanation:

This is because oxygen will not be available for breathing and energy will not be released for cellular activities because photosynthesizing organisms have chlorophyll and trap light energy ffrom sunlight , using carbondioxide and water to produce glucose and oxygen. Oxygen is the by product which is the gas that is inhaled by living organisms during respiration and also break glucose to release ATP. Therefore without these organisms, respiration will be difficult.
